To all whom it 'mr/,jy concern.'

Be it known that l, AMBaosE T. MAT- '.rnnws, a citizen of the YUnitedStatesI residingat llloreester, in the rountir of ll'roreester and StateolE Massaehnsetts, have invented a new and nselfnl Ball-Bearing', ol'Whieh the followingI is a speeiliention.

This invention relates to that Class of ballbearings whieh are intendedto be manulaetured and sold :is articles ol: manufacture, ready for usein niarhinei'y or in other situations where the saine are to be applied.

'.ihe esrnwial object of this invention is to provide a ball bearingeene with a washer or ring' l'or holding' the parts of the bearing tog(.en

lo 'this end, this invention consists of the lmil-lieariinr as anarlirlo ol' imimllaotnre, und ol the eombiinttions ol' parts therein nshereiinrlter deseribed and more partioularbT pointed ont in the claimsat the end of this speeiliention.

ln the accompanying dra.' ing, Figure l1 is a side view partially instation of a ballbeminx;Iv eonsti'nrled aerordinpr to this invention.Fig. 2 is a 'perspective view of the ballbearino' one and its holdingwasher in its original l'oi'm. in sertion showing' the manner in whichthe ball one and its washer are put together. lilies. l, 5 and (i areperspeetive views illustratingsligrhth' modilied l'orins ofconstruelion.

ln the use ol' mil-bearings, and especially in making' that ela-ss ol'ball-bearings which are intended tolle plnred npon the n ai 1iet :isdistinet artirlesol' mannl'aetnre, it has heretofore been eustonmry toemploy balleagres or ball-ret:lining deviees ol various kinds l'orprmf'enting;` the ballsironi dropping ont of 'hositiou These bell-eavesor ballretainers have heretofore usually )een sprung into plare toengage the bearing-balls themselves.

The use ol' these ball-retainersl have l'onnd to be objectionablebeeause when not properlyv adjusted they liable to be engaged by thebearing' balls so as to increase the l'rietion thereof, or in othereases, these ball-retainers 'or ball-cages arelliable to beeomeloosened.

lo over-come these objections in a ball bearing eonstr'neted accordingto inv invention l have provided the Aball-bearing cone with a retainingWasher or ring. This retaining washer or ring engages the rear side l*1ig. 3 is n side View partially,

` of the ball easing and will eliieiently hold the parts together; whileat the saine time, it will not interfere or in any wav be liable to comeinto 'Contact with the bearing balls running in the ball-easing ortrack.

Referring to the accompanying .drawing and in detail, shown in Fig. l,the bollbearing` Constructed accordingl to this invention comprises theball-hearing cone l() which is adapted to be secured to the stud orshaft; the ball-easing' or traek 11 which is to be secured to the boxolthe stud or shaft; and the series ol halls 12 which are held in placebetween the ball-cone l0 and or track 11. The bod)r portion ol theballbearing cone l0 extends through the central opening in theball-easing or track il.

ln assembling a ball-bearing ol" this kind, the bearing balls aredropped into place, and when the ball-bearingr eone oeenpies its Theseparts oi' the ball-bearing; are oi substantially the ordinaryconstruction, and are preferably made from hardened steel. W'hen theball-hearing eene has been put in place, the extrenie .hardness thereofprevents the saine from being' pinned, headed over, or otherwise lockedin plaee by ang7 means which would require the cutting or ehang'inCr ofthe shape thereof, and in order to avoid this objeetion, and at thesaine time provide for fastening' the parts together in a simple andellieient manner, l employ a l'iolding washer or ring; This holding'washer o1' ring `praetiee, it is preferaliily made of tapering' orronieal shape lniv'inl a eentral (niening'whieh is large enough toreceive the bodyv portion ol" theball-bearing Cone 1G, the conical sha)e of the fastening1 washer or rinI causing' the same to be eontraeted`firmly on to the body portion of the eone when the ringr is flattenedo1' pressed to iinal position. Diiierent means inav be provided forpreventing;I the fastening washer from slippinf.v For example, asillustrated in Fig. l, the 'iall-bearing cone 10 is providedvith aslight turned over holdinghead or ilange 13.

The fastening' Washer 14, as shown in Fig. A2, is of a tapering orconical form, and has its een trai opening of sniicient diameter topermit the saine to be slid on to the end of the body portion of theball-bearing cone, as shown inFig. 3. 'These parts are so proportionedthat when the fastening va-Sher or ring 14 is flattened or pressed tofinal posithe hall-easing may be of different constructions, butinnormal position the halls will beheld in plaee.

in. the modieetion illustrated in Fig. 5, the helhheoring eene l() isprovided with smell holee or sockets i6 for receiving inte* gral ,keysor pins .i7 which extenclin from the body portion ol the holding Washeri4. In other eze, especially in smaller sizes of hearings, l have found.that no special ineens ...eetl he employed for preventing the festeningweelzer Slipping; 'the end oi the hellhearing cone. Thot is to say, esillustrated Fig. 6, the body portion ot the bnlhbeering eene may loe oistraight eylindrieol form, sind. the fastening 'washer lei. when )pliedthereto will he gripped or pressed thereon 'with Snilicieht firmness sothat friction alone will prevent the seme from slipping oil' of iteapplied position.
